WRITING MACHINE.

Application led October 23,

To all whom z't mag/'concern' Be it known that I, HJALMAR ELMBLAD, a citizen of the United States, and resident of Chicago, in the county of Cook, State of Illinois, have invented new and useful Improvements in a lVriting Machine, of which the following is a specification.

This invention relates to a machine especially adapted to selectively print large letters or characters. one at a time, and pertains particularly to the spacing mechanism whereby just spacing ma be obtained. The invention disclose( herein pertains to the type of writing machine shown in Patent 1,352,405, granted to me September 7, 1920. 4

It is the principal object of this invention to provide a spacing mechanism which is simple, compact in structure, and positive in operation. These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawings, in which:

Fig. l isa plan view of a complete machine; Fig. 2 is a plan view on an enlarged scale of details of the vspacing mechanism; Fig. 3 is a front elevation of a complete machine; ?Fig. et is an enlarged elevation of the mechanism shown in Fig. 2, a vertical section lthrough the table being shown; Fig. 5 is a side elevation of the complete machine; Fig. 6 isa section seen on'thc line 6-6 of Fig. 2; Fig. 7 is a vertical section on an enlarged scalesliowing a fragment of the machine as seen on the line 7-7 of Fig. l; Fig. 8 is a vertical elevationl on an enlarged' scale of details of the spacing actuating mechanism. parts being in section 0n a broken line which will be understood from the detailed description; Fig. 9 is a view similar to IFig. S showing the actuating mechanism in another position; Fig. l0 is a plan view of\ a fragment of the table showing details of the paper' carriage; Fig. 11 is a section as seen on the line ll-ll of lFig. 10; Fig. 12 is a section as seen on the line 12-12 of Fig. it).

Broadly the machine comprises a wheel carrying type on its periphery, which .may be depressed, when the proper type is in position for printing. carriage for` paper is provided with suitable mechanism for advancing the paper under the wheel after type impressions are iliade.

The table which supports the mechanism 1922. serial No. 596,349.

is indicated by A. Mounted upon the table is a head B. yThe latter supports a type wheel C in such a manner that it may be rotated, depressed and elevated in a vertical plane for making a printed impression. The paper is moved over the table b means of the 'spacing mechanism indicate generall by D.

leferring more particularly to Figs. l, 3, 5, and 10, the table A comprises a top 14 supported upon sills 15 and 16 which ex'- tend from the front to the back of the table. Mounted upon the sides of the table so as to slide thereover are vtriangular plates 17 connected at the front by a cross piece 1S upon which a scale is marked. Rails 19 are secured to the plates 17 and overhang the sides of the tablel so as `t-o guide the plates in their Sliding movement backwardly and forwardly on the table. To preventdisvplacement of the plates, lugs 2O are secured thereto and engage the sides and bottom of table 414. An adjustable cross bar 21 is secured to the plate by means of bolts and wing nuts indicated by 22. Cross pieces 18 and 21 are giooved, see Fig. 5, t0 guide and retain the paper therein. Formed in the table at the place where impressions are made, is a recess 23 covered by a housing plate 24 for feed rollers, see Figs. 4 and 6. The housing plate is rovided with openings and disposed therein with their peripheries elevated slightly above the surface of the plate are feed rollers 25, these rollers being journalled in the table. The rollers are for the purpose of aiding smooth movement of the paper over the table.

Mounted upon the table is the head B for carryingjhe type wheel-and spacin mechanism. his head comprises a hoiilow upright arm 26 which is provided with a hollow forwardly extending arm 27. Secured to the forward end of the arm 27 and depending tlierefroin is a plate 2S. Secured to the plate at the sides thereof are guide lugs 29, which form ways for a plate 30, to which the type wheel is secured. The 'type wheel is joui'nalled upon a pintle 31, see Fig. 7, which is iixedly secured to plate 30 and has a stub 32 disposed in the bore of arm 27 of the standard'. Engaging the stub 32 and tending to hold the tvpe wheel iii its upper position isa leaf spring 33. This sprin'g rests on a fulcriim 34, the rear end thereof being supported in a sleeve 35,v which rests against an adjusting screw 36. By adjusty form spacing.

ing screw 36, the tension of the spring may be adjusted. Slidably mounted in ya bore adjacent the forward end of the spring 33 is a pin 37 for engagement by a copy holder later described. Wheel C is j ournalled upon pintle 31, and key 88 extending,r through the pintle holds the type wheel against displacement. 'Secured on the hub of the type wheel is a sleeve 39 having at lts outer end a handle 40. The sleeve is held 'in position by a set screw 41. The type wheel may be rotated and depressed by manipulating the handle 40. On the outer face of'the wheel are type bearing characters for printing, and the characters are also marked on the inside of the wheel in corresponding positions. Cut into the rim on the front side of the wheel are guiding and spacing notches, one for each character. These notches are for the purpose of properly guiding and spacing` the letters or the characters as they are prlnted. j The spacing as herein shownl is not uniform, but varies directy with the .width of the characters and is hereafter called just spacin to distinguish from uni- T e operation of the notches in cooperation with the other elements of the. spacing mechanism will be described later. 5 f e Referring particularly to Figs. 2, 3. 4, 6, 7, 8, and 9, a frame 42' is secured to plate 28. This frame has forwardly extending arms 48 and 44 connected by a cross lpiece 45. An extension 46 of the frame disposed to the rear, is preferably vmade integral therewith, with ay rod "47y serving as a slide fora bridge 48 mounted thereon. The bridge is provided with a -roller 49 and is fixed to'an L shaped arm 50 by means of a set screw 51.

Secured to one side of extension 46 and to ablock 52 fixed on the end of arm-50 is a tension spring 53. The tension spring tends to move arm 50 outwardly. The forward end of arm 50 is `provided with a collar 54 slidably mounted upon a rod 55. 'A nut `56 is mounted upon rod to abut the collar. lod 5,5 has secured thereto a collar 57, and disposed between collars 54 and 57 upon the rod is a'spring. 58.4 By this'means, the rod k55 is yieldingly secured to the arm 50. Rod

55 'is slidably supported at each end upon l guides 59 and 60 which ride upon bar 45.

A frame 61 consisting of a plate and brackets is slidably mounted on bar 45.

straps 62 holding it in position. Disposed below bar 45 -is a paper feed dog 63. It comprises a Abar. having teeth on its lower face to engage the paper. lt is so mounted that it may be moved up or down. A lever :1u-m64 is pivotall'y secured thereto as indicated by 65.` Arm 64 is pivotally mounted r upon the framev611at pivot point 66. vBy

y:frontend toscale 18,A forming a part df the '.paperfcarriage; Dog-90 .has apertures for `ally secured to 'erin-64 may engagge ai notch68 on the top of frame 61. When the.

fcatch is disposed in notch 68` it maintains one end to lever 64 and at the other to frame 61. This spring tends vrto hold arm 64 in such position that feed dog 63 is depressed. A retarding dogQ 73 is pivoted on bar45. It has a collar 74 secured thereto, 'andk a spring 7 5 which presses the dog against the paper. Anelevation 76 on plate 24 is in registry' providlnga better grip on the papel. Disposed on the table to form the impression surface is a pad 77 preferably of rubber or felt glued on'a steel plate. The lower-end of arm 64 is disposed under retarding dog' 73 so that when the feed dog63 iselevated by the arm 64,'ret`ardingldog 73 will also be elevated. This position of the parts Lis shownin full lines in F ig. 4 and allows free movement of the paper. The dotted lines show the dogs in action on the paper.

A spacing hook 78 measuresl the distance the paper is to 4be moved for each letten with the retarding arm, thereby Hook 78 rides on the outer face of the wheel y C and arrests motion of frame 61 b engaging in one of the notches on the wheel. Hook 78 is pivoted on frame 61. y lts pivot pin vhasan arm 79 fixed thereto which is secured at one' endby a spring 80 -toithe frame. The spring 80 through arm 79 raises hook 78 and keeps an upward tension on it at all times.

A lever handle 81` is pivotedfon bar 45 and engages strap 60.v Spring 82 tends to main-- tain the handle out of engagement with the strap. 'By swinging handle 81, frame 61 may be moved independently of the type wheel, rod 55 sliding through collar 54 which remains stationary.'lrVhen printing, forward motion of frame 61is derived from spring :S3-through Vrod 1.50. Armi-83 is 'pivoted on arm 27 of head B, as indicated by 84. The upper end thereof has a roller 85 riding on plate 30. The lower end engages roller 49 on frame D. Arm 83 brings the frame D back to 'its original position and prevents too rapidv forward movement of frame 1,61.

`A guide pin 86 is fixed to bar 45 and passes r.

through the notch of the character being printed This exactly locates each charfacter. lever 87 is pivoted to frame D at 1 88. Mounted on lever 87'by a loose pivot pin 89 is \a clamping dog 90. Dog 90 is mounted on a rod 91 which is securedat its the rod 'of such diameterthat the dog may .by holding the dog loosening screws 22 and moving the be rocked to the position shown in dotted lines in Fig. 11. In this position, it grips rod 81, and the paper carriage may thereby be moved a line. A tube 92 secured to table A has rod 81 telescoping in it and guides the latter in its movement.

Inking rollers 93 bearing against the face of the type are mounted in a housing supported upon an arm 94. Any other suitable means for inking may be employed. Friskets 95 and 96 prevent type adjacent to the one to be impressed from printing.

The type wheel may be removed and a wheel having a different style of type installed. 4This is accomplished by removing set screw 41 and slipping sleeve 39 and handle 40 from the hub. ley 38 may then be removed. To dispose and hold the type wheel in such position Ithat it may clear the inking rollers and spacing mechanism, copy holder arm 97 is swung downwardly to engage plunger pin 37 which acts upon spring 33 depressing `the wheel to the position shown in dotted lines in Fig. 7 permitting the wheel to be slipped from pintle 31.

The handle of arm 64 is moved to the right so as to lift feed dog 63 from rollers 25 and permit catch 67 to drop into notch 68, there- L in its upper position. The sheet of paper to be printed upon is placed with the lower edge in the groove of cross-piece 18 of the paper carriage and the upper edge in the groove of cross-bar 21. The latter is adjusted as to position by bar 21 to the proper position, then tightening the screws. The entire paper carriage, including plate 17 is then moved so that the letters on the type wheel are at the proper line positions on the paper. The paper is then slipped along the cross-bars until in position for printing the first letter or character. Type wheel C is rotated to bring the letter to be printed and its notch in registry with pin 86, and the wheel is then depressed thereby printing Ithe desired letter. 0n depression of the type wheel, plate 30 is moved downwardly, see Fig., 9. This causes the lower end of arm 83 to swing outwardly and to permit-bridge 48 to follow the arm to the right. The bridge being fixed to arm 50.is caused to move therewith by reason of the tension of spring 53. lVhen arm 50 is moved to the right, it moves rod 55 to the right. and drags frame 61 to. the right by reason of the connection of the rod through "he bail and pin 71. (latch 67 is engaged b v release 69 which is fastened to bar 45, and is raised from notch 68. The frame is moved to the right until hook 78 engages the notch on the Wheel in registry with the character next to the right from the one just printed. This limits the movement of the frame. The distance between notches on successive letters or characters measured in a clockwise direction about the type wheel is arranged according to just spacing. Upon releasing pressure on the handle 40 0f the type wheel, spring 33 moves it upwardly. This causes late 30 to be moved upwardly, and arms 83 1s rocked into the position-shown in Fig. 8. T his causes bridge 48 to be moved to the left and likewise rods 50 and 55. Bail 70 on rod first rocks arm 64 and moves feed dog 63 against the paper restingon rollers 25, and further swinging of the arm 64 is inhibited by reason of dog 63 resting against the paper. Further movement of rod 55 to the left causes the frame 61 to be dragged alon by reason of the connection with the ro througlr bail 70 and pin 71. The result is that the paper is moved by feed dog 63, which presses thereagainst and is vdragged to the left a distance equal to just spacing. The

wheel is then rotated to position for prin 85 ing the next letter.

Suppose it is desired to space between characters, the handle of lever 81 is grasped and rocked to the left. lThe lower arm of the lever presses against guide 60 and moves rod 55. The latter slides in collar 54 against, the action of spring58. The frame 61 `/is then moved to t-he right in the manner before described. Spring 58 returns rod 55 and the paper thereby vmoves one space. To

move the paper to a4 new printing line,

lever 64 is moved aper, catch 67 dropping into notch 68. andle 87 is then pushed from the operator,

rocking dog 90 so as to grip yrod'91 and move the paper carriage away from the operator.
